' Letters Patent No. 84,049, dated November 17, 1868.

IMPROVE!) CAR-COUPLING. fl The Schedule referred to in these LettersPatent and making part of the same.

To all persons to 'whom these presents may come Be it known that I, JOHNH. GHADWICK, of Bristol, inthe county of Bristol, and State of RhodeIsland,have invented an Improved Railway-Carriage Coupling; and dohereby declare the same to be fully described in the followingspecification, and represented in the accompanying drawings, of which-Figure 1 is aside elevation,

Figure 2, a longitudinal section, and

Figure 3, a front elevation of a railway-carriage drawbar with myinvention applied to it.

In such drawings, A denotes thedranbar, having within it a chamber, B,provided with a flaring mouth, C. The mouth, at its junction Ii with thechamber, is rectangular in shape, and the ont endof the chamber is avertical plane.

b A 1passage or slot, c, leads out ofthe top of the cham- A lever, D,provided with two curved armsb c, extended from it in manner .asrepresented in fig. 2, is arranged within the chamber B, and projectsout of the chamber, or through the slot a thereof, in manner as showninithe said figure.

rllhe upper arm f of the lever has a weight, e, fastened to it, therebeing a staple, g, projected from the weight for the purpose ofattaching a rope or a chain, h., to the Weight. A

The fulcrum d of the lever D is a pin going through the'lever and thetwo opposite sides of the chamber B.

'lhe draw or connection-rod E, used to eii'ect the coupling of two carshaving draw-bars provided with a chamber and coupling-lever, made andarranged substantially as described, is' shown at E, it being furnishedwith two projections or shoulders l l, and two wedged v or'pointed rodsk la, v formed and disposed as shown in vfig. 2. f

When the connection-ibex E, which projects from the draw-bar of onecarriage isin the act of being moved toward and into the chamber ofthedraw-bar of another carriage, the forward nose k of the bar E will beforced against the lower end of the auxiliary arm c of the lever D, andwill thereby move the lever on its fulcrum, so as to enable the nose kto pass into the circular space between the arms b c. The bar Econtinuing to advance, will move the arm b below the fulcrum (l, andconsequently will move the lever 'in an opposite direction, and the barE down, so that when next pulled back, such bar E will catch upon thepart, "n, between the mouth c and the chamber B thereof, and therebycii'ect the coupling of the bar E to the draw-bar.

The weight e, with the auxilliary arm c, serves tokeep the bar. E inconnection with the part, nl.. On-

raising the weight and the arm f of the lever D, the arm b will beforced against the nose 1c of the bar E, so as to elevate the .shoulderl of such nose above thc abut' ment or part, fin, and thereby enable thebar E to be drawn out of connection with the draw-bar.

1 am aware of the invention described in the United States' patent, No.5,961, dated December 12, 1848, and granted to Daniel R. Pratt, for acar-coupling, and make no claim thereto.

With my invention it will be seen that I do not employ an open link forconnecting the two. carriages, and that my coupling-bar E catches orhooks upon a part,

"In, of the draw-bar, in order for the connection of such two bars.Also, that while the cars are coupled, it is so held in connection bythe lever D.

'I therefore claim the arrangement and combination ofthe arms b c, andpart or abutment, fm, with the lever D, the draw-bar chamber B, and itsmouth O, substantially as described, the whole being`to operate inmanner and for the purpose specied, with a connectionbar,- E, made asset forth.
